Trade Lead Description:
Gum Rosin
H. S No.: 38061010
Molecular formula: C20H30O2
Molecular weight: 302.44
Usage: Uses of Gum Rosin: At
present, most rosin product is
used for the manufacturing of
paper, paint, soap and printing
ink. Since rosin is easily
softened and oxidized, in the oil
paint industry, the
carboxylation reaction of resin
acid is usually employed to
produce resonates for further
use. While in the producing of
synthetic rubber and printing
ink, resin acid is changed into
disproportionate rosin, polymerized rosin, hydrogenated rosin, etc for
further use by its double bond
reaction.
Storing and Transporting: Gum
rosin must be kept away from
heat and flame.
Package: Packed with
225/230kgs net each
galvanized iron drum.
